Abstract
The nucleotide sequence of the leuD gene of Salmonella typhimurium and of the downstream flanking region are presented. S1 mapping experiments identified 3′ endpoints of leu mRNA 140 and 285 nucleotides downstream of the UAA stop codon of leuD mRNA. Experiments employing pulse-labeled RNA suggest that these endpoints result from transcription termination rather than RNA processing. Our results indicate that the organization of the 3′ non-translated region of the leu operon from S. typhimurium resembles that of the trp operon of Escherichia coli. Further, our results suggest that the leu operon of S. typhimurium does not contain structural genes other than those identified by genetic experiments, i.e. leu,A,B,C and D.This publication has 76 references indexed in Scilit:
